Use your mouse as magnifier, color dropper and distance analyzer. MouseZoom is a nice small utility. It zooms the current mouse position (up to 50x), and shows the color value (RGB, HEX, HLS, CMYK), and the absolute and relative position of the point where the mouse is. MouseZoom is available in English and German language (auto detection). That software doesn't record activities, doesn't require runtimes, doesn't require installation, doesn't write to the registry, and doesn't modify files outside of its own directories.
Editor's review of MouseZoom Get a closer look with MouseZoom, a handy freeware utility that displays a magnified view of the screen beneath your cursor. In addition to magnifying, MouseZoom gauges the distance between pixels and indicates the color of the nearest pixel in RGB and CMYK notation--useful for graphic designers. Unlike Windows Magnifier, MouseZoom lets you move and resize the program window. It lacks hot keys for zooming in and out, but on the upside it doesn't require installation. Vision-impaired users should be aware that the magnified view appears in a separate window rather than directly beneath the cursor, so it's not the best reading aid. MouseZoom is really designed for artistic types who want to get details pixel-perfect.
